VEHICLE-WHEEL.

Specification of Letters Patent.

Application filed September 17, 1906. -Serial No. 335,022.

To all 'whom t may concern:

Be it known that I, THOMAS B. JEFFERY, a citizen of the United States, residing at Kenosha, county of Kenosha, State of Wisconsin, have invented a certain, new and useful Improvement in Vehicle-Vheels, and declare the following to bea full, clear, and exact description of the same, such as will enable others skilled in the artto which it pertains to make and use the same, reference being had to the accompanying drawings,

y which form apart of this specification.

My invention relates *in general to vehicle wheels and more particularly to a detachable pneumatic tire rim.

In the use of pneumatic tires inconvenience and labor are occasioned by punctures, as it is then necessary to remove the tire from the rim and secure thereon a new tire, or when a double tube tire is used it is necessary to detach the outer casing from the rim and vto remove and repair the punctured one, after which the tire must be in- Hated. Considerable time and trouble are consequently occasioned by the puncture of any form of pneumatic tire at present on the market.

The primary object of my invention is to provide a vehicle wheel around which a fully inflated pneumatic tire may be quickly and easily secured, thereby avoiding the necessityof repairing a punctured tire on the road and of intlating the repaired tire or a new one substituted for the punctured tire.

A further object of my -invention is to provide -means for detachably securing a pneumatic tire rim directly to the spokes of a wheel, thereby permitting a lat tire to be readily replacedby a fully inflated tire.- A still further object of myinventionis to provide means for detachably securing a pneumatic tire to a vehicle' wheel which will be simple in construction, inexpensive in lmanufacture and eiicient in use.

The embodimentof my invention-herein disclosed may be generally described as comprising a` metal pneumatic tire rimof any suitable construction, adapted to be secured concentrically around the ends of the spokes of a wheel, a pluralityof clamping plates secured to the interior surface ofthe 'rim and alining with the spokes, and spokeheads adjustably secured to the ends of the spokes and adapted to be removably secured to the interior surface of the rim by the clamping plates. 'i My invention will be more` fully described hereinafter with reference to the accompanying drawings 'in which the same is illustrated as embodied in two convenient and practical forms, and in which#- Figure l is an elevational view; Fig. 2 an enlarged detail view on line 2 2 Fin'. 1; Fig. 3 an elevational view of the wheel, the rim and tire having been removed therefrom; Fig. 4 an enlarged plan view of the under surface of the rim adjacent to one of t-he spokes, the spoke being shown in section; Fig. 5 a sectional viewsimilar to Fig. 2 showing amodification; and Fig.y 6 a detail view of one of the clamping plates.

Patented J an. 2,1912.

- Similar reference 4characters are used to and detachably supported in any suitable manner upon the rim C. So far as my 1nvention is concerned the tire may be of any desired type either single or.mdoubletube,

j and may be secured in any suitable manner to the rim C.

Adjustably secured to the interior surface ofthe rim C are clamps E adapted to engage the spoke heads b and secure` the Vsame tightly to the rim. The; clamping plates may convenientlybe of the shape shown in lfdetail in Fig. 4 1n whlchqa-n opening is provided extending from one end to the centerA of each plate, the width of such opening beingless than the diameter ofthe spoke-heads. The clamping platesE maybe conveniently secured to'the\rim C by means' of bolts e extending through registering holes in the rim and plates. VThe headslA of the vbolts are shown as overlyingthe4 outer1 surface of the rirn,1 while theends of-the Vbolts which eXten'dt-hrough. the Clamping plates lare provided with nuts. T heclamping plates are preferably provided with shouldersvv or ribs E Whichengage the edges of the respective spoke-heads and thereby prevent the spoke-heads from working outwardly with respect to the slots-in the correspending clamping plates.

When it is desired to remove the rim from the. wheel the nuts on the bolts which secure the clampingplates to the rim are unscrewed so. as to permit the clamping plates to be moved away from the under-surfaces ofthe spoke-heads. The wheel and rim are then relatively rotatated so that the spoke heads will pass out of the lslots in the clamping plates. The rim 4may then readily be removed from around the ends of the spokes and a new rim located around the ends of the spokes and secured to them relatively rotating the rim and wheel so thatl the spoke heads will pass into the slots in the clamping plates. .The nuts are then tightened 011 the -bolts'so that vthe'spoke-heads will be of the slots in the plates.

securely held between the inner surface of the rim and the clamping plates.

The clamping plates are preferably -so located with respect tp the direction in which the wheel normally ,rotates that the spoke heads will loe-forced against the inne-r edge Any danger of vv the spoke-heads working out lo'f the slots,

as for instance when the vwheel is rotated in a reverse direction, is prevented by the ribs on the plates. i

In Fig. 5 I have illustrated a modification ofmy invention in which'the spoke-heads are radially Aadjustabl-y secured `to the sockets. In Fig. reference characterr B indicates one of the sockets on the end ofp a spoke a while b indicates the vspoke-head carried by the socket. The spoke-head 1s v provided with an exteriorly screw-threaded shank b2 whichvengages an interiorly screw-4 threaded sleeve' formed concentrically on the socket and extending into the endof' the spoke. 'By adjustably securing the spoke heads to the spokesthe length of the spokes may be .varied to adapt the 'same to different sizes of rims. The adjustment of the spoke-heads also facilitates the removal of the rim, and when a rim,` hasfbeen located around the spokes enables the sameto' be closely engaged'by the spoke heads."

, By means of my invention itis possible fora vehicle such as an automobile to carry the road or todetach the same from its rim -and substitute a new tire around the rim.

thereto, as I contemplate changes in form,

the proportion of parts, and the substitu-V tion of equivalents, as circumstances may suggest or render expedient, without departing from the spirit of my invention.

Havingnow fully described my-invention, what I claimy as new, and desire to secure by Letters Patent is:

1. The combination of a self sustaining 'wheel body consisting of a hub havingradially projecting spokes thereon, heads on the ends of said spokes, a rim having an iniated pneumatic tire thereon, and radially adjusted clamps on the inner surface of said rrm in position to engage and .clamp the heads on the spokes against the inner surface of the rim, each of said clamps being provided with an open-ended slot and with ashoulder on one side of the slot on the face adjacent to the rim for the purpose of eigtaging the side of thelhead opposite the s o. 1

'-2. The combination with awheel body comprising a hub having spokes radiating therefrom, of heads on the ends of vsaid spokes, a rim surrounding said spokes adjacent to said heads, and a'series ofclamping plates carried by said rimfo'r engaging with the inner sidesv of said heads, each of said clamping plates having an open-ended lslot.for the reception of the spoke and a shoulder extendingtransversely to the length of said slot on ,the side of the plate adjacent to the rim" for engaging with the corresponding head when the plate is se cured -to the rim.

4. The combinationof a wheel body coinmeans for securing said jaws to the rim and prising a hub :and spokes, of a rim 'are ranged about the outer'ends of the spokes, 4 f i a series of open jaws' `arranged upon the inner side of the rim for receivingfthe ends of the spokes, said spokes having upon the -ends shoulders extending transversely tothe operative relation to the shoulders onthe plane of the wheel and said jaws having on spokes.
